Systems and methods of determining locations of medical devices relative to wearable devices

1. A system for directing emergency personnel to at least one medical device, the system comprising:

a medical device comprising

one or more first antennas; and

one or more first processors coupled with the one or more first antennas, the one or more first processors being configured to

receive, via the one or more first antennas, first location information from a first location information source external to the medical device, and

determine an estimated location of the medical device based on the received first location information; and

an external device configured to direct emergency personnel to the medical device, the external device comprising:

one or more second antennas; and

one or more second processors coupled with the one or more second antennas, the one or more second processors being configured to

receive, via the one or more second antennas, second location information from a second location information source external to the external device,

determine an estimated location of the external device based on the received second location information, and

receive, from the medical device via the second one or more antennas, information descriptive of the estimated location of the medical device.

2. The system of claim 1 , wherein one or more of the first location information source or the second location information source comprises one or more of a GPS source, a cellular network source, a satellite, a wireless local area network access point, a Bluetooth source, or an RFID tag.

3. The system of claim 1 , wherein the one or more second processors are further configured to transmit, via the one or more second antennas, the estimated location of the external device to at least one server.

4. The system of claim 1 , wherein the one or more second processors are configured to determine a path between the estimated location of the external device and the estimated location of the medical device.

5. The system of claim 4 , wherein the external device further comprises a display and the one or more second processors are configured to provide the turn-specific directions via the display.

6. The system of claim 5 , wherein an arrow is provided on the display to indicate at least one of the turn-specific directions.

7. The system of claim 4 , wherein the external device further comprises a speaker.

8. The system of claim 7 , wherein the one or more second processors are configured to provide the turn-specific directions as audible instructions via the speaker.

9. The system of claim 4 , wherein the one or more second processors are configured to provide turn-specific directions descriptive of the path.

10. The system of claim 1 , wherein the one or more second processors are configured to transmit, via the one or more second antennas, a notification to the medical device when the external device is within a threshold distance of the medical device.

11. The system of claim 10 , wherein the one or more first processors are further configured to issue the notification as an audible sound so as to assist the emergency personnel to locate the medical device.

12. The system of claim 11 , wherein the audible sound is an alarm.

13. The system of claim 1 , wherein the one or more second processors are configured to determine a shortest path between the estimated location of the external device and the estimated location of the medical device.

14. The system of claim 13 , wherein the one or more second processors are configured to determine the shortest path by analyzing map data stored in a memory of the external device.

15. The system of claim 1 , wherein the external device is a wearable device.

16. The system of claim 1 , wherein the external device is a phone or tablet.

17. The system of claim 1 , wherein the first location information received from the first location information source comprises an identifier for the first location information source, and the estimated location of the medical device is determined at least in part from a geographic location stored in a location database for the first location information source corresponding to the identifier.

18. The system of claim 1 , wherein the one or more first processors are further configured to receive third location information from a third location information source different from the first location information source.

19. The system of claim 18 , wherein the one or more first processors are further configured to rank the first location information source and the third location information source according to a hierarchy of location information sources.

20. The system of claim 19 , wherein the one or more first processors are configured to determine the estimated location of the medical device based on the received first location information in response to the first location information source having a higher rank than the third location information source.

21. The system of claim 19 , wherein the one or more first processors are configured to determine the estimated location of the medical device based on the received third location information in response to the third location information source having a higher rank than the first location information source.

22. The system of claim 18 , wherein the one or more first processors are further configured to improve an accuracy of the estimated location of the medical device based on the third location information.
